A problem has recently cropped up in my DNN 5.02.03 installation running my company's Intranet - the AD Authentication module I'm using (5.0.2) DOES authenticate the AD user automatically (open the browser - user's name appears at the top...), however if I hit 'logoff' and then try to use the Windows Login button (put in domainname\user and password), login fails.

I've made no changes to DNN for a long time and this has always worked. But it has inexplicably stopped working. Does anyone have any ideas why this might be happening?

Thanks

AD password is minimum 8 characters, but that has never been a problem. No changes have been made on my DNN server recently - this just started happening for no reason I can see.

In order to see if an upgrade will take care of this I've copied my production site over to a test site, upgraded the DNN framework from 5.2.3 to 6.2.7 and downloaded the AD Auth. Provider v. 5.0.5.

I haven't done this in a while, but I can't find how you upgrade the Auth. Provider - the Extensions page shows the current provider but doesn't show that there's an upgrade available so there's nothing to click on to upgrade. And I can't find any other way. How is this done?

Thanks
